Unit focus

  • Repeated experiments show variation: identical chance conditions can produce different short-run results. Larger combined samples often give a more stable picture of outcome relationships, but exact frequencies are not guaranteed.
  • Use this routine: Define outcomes → Predict → Conduct consistent trials → Record frequencies → Repeat/aggregate → Compare proportions → Describe variation.
  • Watch for equal chance means equal every run: Small samples can vary considerably.
